It's possible to create a policy which can no longer be used to mint/burn after a given slot. The following object in a policy.script handles that:

      "type": "before",
      "slot": <insert slot here>

What if, however, one does not include this block (no before object in script) but eventually wants to lock the policy to prevent future burning/minting? Is this possible?

Nope. The contents of the script itself are used to actual generate the Policy ID. Once you mint something under that policy ID it's impossible to make a change.
